Question:

What is the SYSVAUX address space? How can we use it?

Answer:

SYSVAUX is the Auxiliary Services Address Space. Multiple auxiliary address spaces can be used when needed.
The auxiliary address space can run CICS logger tasks.

Server address spaces connect with UNIX system services in case they are needed for some reason.
Additionally, SYSVAUX is used to run multiple CICS Logger tasks, which are vital if you run many CICS regions which are high volume regions.
Multiple Auxilliary address spaces can be started and run if need be.


SVW$AUX is one of parmlib members for Auxiliary Address Space Initialization Parameters.
The SVW$AUX provides the CA SYSVIEW auxiliary address space with initialization information.

SVW$AUX member:
The SVW$AUX member is used to provide address space initialization parameters.
Start commands determine whether individual components are started during initialization.
This member is associated with the SYSVAUX procedure (There is sample JCL for the STC in prefix.SAMPJCL ).
The definitions that are contained in the member determine which additional components and subtasks are started or enabled.
